JOHN \VESTER, OF TRIUMPH, MINNESOTA.

SACK-HOLDER.

SPECIFICATION forming part of Letters Patent No. 639,120, dated December12, 1899. Application filed March 30, 1899. Serial No. 711,144. (Nomodel.)

To ctZZ whom, it may concern.-

Be it known that 1, JOHN WESTER, a citizen of the United States,residing at Triumph, in the county of Martin and State of Minnesota,have invented certain new and useful Improvements in Sack-Holders; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to sack or bag holders.

The object of the invention is to provide a convenient means for holdinga bag or sack while it is being filled, and particularly to hold thebag-supporting jaws in their operative or extended position by means ofa strong spring which is so arranged that when the jaws are closed orbrought toward each other the same spring will hold them in the closedposition.

Another object is to provide means for adjusting and holding the headand jaws at any desired elevation in a convenient manner and at the sametime permit the spindle to be rotated or swiveled in the standard.

A further object is to provide jaws which will hold the sack withoutserrations or teeth, which have the effect of chafing and injuring thefabric of the bag.

To this end my invention consists in the combination of a suitablepedestal or base, a tubular standard extending upward from the base, aspindle telescopically coupled with the standard having a lateral arm, apair of arms or jaws pivotally connected with the arm of the spindle, aspring device coupled with the arms or jaws in such way that when thearms are closed or brought near together they will stand at rest, butwhen slightly distended the spring will operate to throw the arms andjaws outward to grasp the interior of the mouth of the bag.

The invention also consists in the combination, with the standard andspindle, of a friction -clutch for automatically grasping, holding, andswiveling the spindle at any desired elevation.

The invention also consists in providing the arms with jaws havingdouble flanges, the

bottom flanges of the jaws serving to grasp the mouth of the bag andhold the same, while the upper flanges project over the top of the edgeof the bag.

In the drawings forming a part of this specification, Figure 1 is anelevation showing my improved bag-holder as applied to use, thefriction-clutch for grasping the spindle being shown in section. Fig. 2is a top or plan View showing the arms and jaws in their outward orextended position. Fig. 3 is a similarview showing the arms in theirclosed position. Fig. 4 is a detail section through one of the jaws,showing the form of the flanges.

1 is a pedestal or base upon which is mount ed and firmly secured atubular standard 2. Telescopically connected'with this standard is aspindle 8, having a lateral arm 4;. This arm as it extends from thespindle part first projects downward somewhat, then in a horizontalplane, and then upward to its extremity, as shown in the drawings. Theextremity is provided with a head, and pivotally connected with the headare bag-holding arms 5 5, having at their operative extremities 1 75curved jaws 6 6, the jaws being formed or provided with horizontalflanges 7 7 for grasping the bag and with inclined flanges 8 S to extendover or outside the mouth of the bag. One of the arms is provided with ahorn or projection 9 near its pivotal point, and the other arm isprovided with a similar projection or horn 10 at a greater distance fromits pivot. A powerful spring 11 is operatively coupled with theprojections 9 and 10 through the medium of relatively movable parts 12and 13 for throwing the arms and jaws apart, as shown in Fig. 2 of thedrawings, and also for holding the arms and jaws in closed position, asshown in Fig. 3 of the drawings. The relatively movable parts 12 and 13are provided with heads or shoulders 14 14:, having sockets or recessesto fit on the horns 9 and 10. As shown in the drawings, the movableparts consistof half'round segments of a cylinder adapted to slide oneupon the other. Obviously the movable parts may be arranged to operatetelescopically one within theother, if preferred. The spring foroperating the jaws is provided with space for movement across thelateral arm by reason of the bend in said arm.

15 is a friction-clutch consisting of a ring loosely fitted on thespindle provided with an arm or finger piece 16, having its innersurface inclined so as to impinge upon the top of the standard and whenresting against the top causes the ring to grasp or bite the spindle andhold thesame at any point to which it may be elevated. The finger-pieceserves for manual operation to release the spindle and permit it to belowered.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a bag-holder, the combination of a standard, a spindle having alateral arm telescopically coupled with the standard, a pair ofgrasping-jaws pivotally connected With said arm, and a spring coupledwith the jaws at different distances from their axis for holding themopen and closed substantially as described.

2. In a bag-holder, the combination of a pair of vibratory jaws providedwith horns or project-ions at different distances from the axis ofmotion of said jaws, and a spring device operativelyconnected with saidprojections for distending the jaws and for holding them in closedposition, substantially as described.

3. In a bag-holder, a pair of vibrating arms carrying curved jaws, eachprovided with a horizontal bag-holdingfiange, and an inclined upperflange, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN WESTER.
